The method may comprise the step of attaching said mounting means to
a vehicle body. ,
The invention will now be described by way of example only with
reference to the accompanying drawings wherein;
Figure 1 is a perspective view of a support assembly according to the
present invention, and
Figure 2 is a view of an alternative configuration of the support
assembly of Figure 1.
Referring now to the Figures, a support assembly is shown at 10,
comprising a support beam 11 having end faces 1?. As seen from the end faces
12, in cross-section the support beam 11 in the present example has five side
.
faces, a forward face 13, upper face 14, lower face 15, upper rearward face 16
and lower rearward face 17. The upper face 14, lower face 15, upper rearward
face 16 and lower rearward face 17 are each provided with a corresponding
groove 14a, 15a, 16a, 17a. The grooves 14a, 15a, 16a, 17a are disposed
peripherally of the beam.
In the present example 'forward' and 'rearward' refer, when the support
assembly is mounted in a forward part of a passenger compartment of a vehicle,
to the directions forwardly of the vehicle and rearwardly of the vehicle, i.e.
away from and towards the passenger compartment respectively.
In the present example, the grooves 14a, 15a, 16a, 17a are generally T-
shaped, although the grooves may be dove-tailed or of any other shape as
desired. The grooves 14a, 15a, 16a, 17a extend longitudinally of the
respective
face 14, 15, 16, 17 along the length of beam 11.
The support beam 11 in the present example is hollow having a
longitudinally extending aperture 18. The aperture 18 is filled with a foam
material 19 for additional stiffness.
. . Although the beam in the present example is . shown as polygonal" in
cross-section, and in particular pentagonal, in cross section, it will be
apparent
CA 02411006 2002-12-06
WO 01/94189 PCT/GBO1/02496
that the beam may have any cross section as desired. The beam may have any
number of grooves as desired, preferably at feast two, more preferably at
least
three, to accommodate modules in a desired on one of a plurality of
.v
orientations.
Preferably, the support beam 11 comprises an extrusion. Forming the
beam 11 by extrusion is particularly appropriate since the beam has a constant
cross-section along its length. Further, since the beam 11 may be cut to any
length as desired, it can thus be adapted to be located in any desirable
vehicle
body of any width simply by cutting the support beam to length. The support
beam 11 may comprise a polymer material, preferably provided with
reinforcing fibres, or may comprise a light metal, e.g. aluminium or alloy
material if desired.
To maintain the support beam 11 in place in a vehicle, the support
assembly 10 comprises mounting means 20. In the present example, the
mounting means 20 each comprise a downwardly extending first part 21 having
an abutment face 21 a and apertures 22 to receive fastening means to attach
the
mounting means 20 to a part of a vehicle body, particularly a vehicle body in
white, and a second part 23 disposed above the first part 22. The second part
23 comprises an inner face 24 adapted to embrace the upper face 14, upper
rearward face 16, lower rearward face 17 and lower face 15 of the support
beam 10. The inner face 24 further comprises tags 24a, 24b, 24c, 24d which
axe received in the grooves 14a, 15a, 16a, 17a respectively. The support beam
11 is thus firmly held in engagement with the second part 23 of the mounting
means 20. The forward face 13 of the support beam 11 and the abutment face
21 a of the mounting means 20 are preferably generally coplanar, to facilitate
mounting of the support assembly 10 on a vehicle body.
The shape of the support beam 11 is thus highly adaptable and can
receive one or more dashboard modules to provide support for any desired
elements to be supported on the beam, for example a steering column, a glove

Referring to Figure 1, general purpose support brackets are shown at 25,
comprising a first connection part 26, a second part 27 spaced from said
connection part 26, and an intermediate part 28. The first connection part 26
is
provided with a tag 29, received in the present example in groove 17a of the
support beam 11, and contact surfaces comprising flanges 30 disposed either
side of the tag 29 which engage the lower rearward face 17 of support beam 11
to minimise relative movement between the bracket 27 and the support beam
11. The first connection part 26 is connected to the intermediate part 28 by
forward arms 31a, 31b. The arms 31a, 31b are angularly shaped such that they
define a four sided aperture 32. The second support part 25 is connected to
the
intermediate part 28 by rearward arms 33a, 33b. The rearward arms 33a, 33b
and the second connection part 25 define a sector shaped aperture 34.
The brackets 25 thus shaped provide energy absorbing properties, and
can be tuned to provide the desired er_ergy absorption. In the present
example,
the forward anus 31a, 31b in particular will flex to absorb the energy of an
impact, in the position shown in Figure particularly of a passengers knee. The
second connection part 27 is provided with apertures 35 to receive fastening
means to attach desired elements thereto, for example an instrument panel,
